Abstract

Searches for scalar top and scalar bottom quarks, as well as for mass-degenerate scalar quarks of the first two families are performed at 189 GeV centre-of-mass energy with the L3 detector at LEP, No signals are observed, Model-independent limits on the scalar top production cross sections are determined for the decay modes (t) over tilde(1) --> c<(chi)over tilde>(0)(1) and (t) over tilde(1) --> bl<(nu)over tilde>. For scalar quarks of the other flavours (q) over tilde --> q<(chi)over tilde>(0)(1) decays are considered. Within the framework; of the Minimal Supersymmetric Standard Model mass limits are set at 95% C.L. for these particles, Indirect limits on the gluino mass are also derived.
